Chapter II: The Nature of Humanity
Although the hidden something which battles against the disintegration of the physical body can be observed by seership alone, in its effects it is plainly evident even to the kind of judgment which is restricted to the outwardly manifest. For its effects are expressed in the form and shape into which the substances and forces of the physical body are combined during life. When death has taken lace, this form gradually disappears and the physical body becomes part of the mineral kingdom pure and simple. Supersensible perception can observe, as an independent member of the human being, what it is that prevents the physical substances and forces during life from going their own way, which would, as we have seen, lead to the disintegration of the physical body. We will call this independent member of man's being the Etheric Body or Life-Body.
